Cannabis Grow Rooms

Red/Blue LED Grow Lights, are they as good as fluorescent and metal vapour lights? Has anyone actually used them? Any tips?

Hi all, Just looking for some advice on the use of fan's with a 'portable split' air con. The issue is, the exhaust fan ducts from a CF, through 2 cool tubes and then exhausts. Which is fine in most situations, until the A/C kicks in and most of the cooled air is lost through the exhaust, so the AC is almost always running to try an cool the ambient temp in the room. Any ideas? Should the exhaust fan be stopped (and a seperate circuit for the cool tubes installed) or just slowed right down using a speed controller?

Got my fridge sorta sorted out and turned on the light tonight....now I had the 400watt CoolTube running this arvo and once agaib I went to turn on and all it would do was glow & flicker and pop now and again? this went on for about 2 mins? fearing there was something with my wireing and the Gremlins had struck again as I tested my 130 CFL n 6 hrs later no start? I Totally Freaked!! Fearing it was my wireing I checked every connection After about 2 minuites I unpluged the underground lead (Twisted togeather and heavly taped at the join) and plugged another lead in , oy flickered a bit ang slowly glowed to life "YAY" Plugged the underground lead nack in and all was g…

hey guys, I've got this fan http://www.aussieponics.com/index.ph...&productId=489 I've bought the silencer, carbon filter *and* speed controller but the bloody thing still sounds like a jet engine!.. I need a *really* quiet fan that can fit a 400w cooltube.. my tent is quiet small so the heat is a problem.. Ideas? Cheers, Jon

After hearing from experienced ozstoner growers about how leds and clfs don't cut it when it comes to flowering i went and tried both. SILLY SILLY FU--ING ME. to any new growers trying to find there feet don't just go by the bulls--t led adds just bite the power bill bullet get a good hps setup and enjoy growing. if only i could roll back time and money but i guess that go's 4 most things.

Hey guys I am looking for some advice I have just built a grow cupboard cause I am sick of paying $300+ for an ounce and I am torn as to which kind of lights would be best. The dimensions are approx 1800x1200x500 so its a decent size but its situated in a tin garage that gets up to 35 constantly so heat is a major issue (cant put it anywhere else though) I will be growing in coco and perlite to start with a view to getting a top fed DWC come winter time. Can anyone tell me how much heat a 400w HID would throw? I am considering Cfls as well as i have heard they are much cooler. Any advice would be greatly appreciated P.S the seeds I have got are critical mass by mr nic…

I was wondering if it would be better to have a lot of small watt cfl's instead of 1 or 2 high watt cfl.

3rd time in the last year Ive had ballasts burn out and melt the wiring at the point the shades plug in causing toxic smoke that kills your plants and might start a full scale fire depending what your ballasts are near , these ballasts are under 2 yrs old and 600 watts in a nice airy postion , Ive read where makers are pumping more juice out of them trying to compete with digital , whatever the reason its not good so watch your ballasts guys they can cause a lot of grief .
